removing one way valve on your map sensor will not effect your afr by much. changing to bigger injector will have a better result. 390cc with safc can boost more than 2 bar if you get the tuning correct. would recommend you to use 310cc injector.hi there,
i was using an one way valve to eliminate my boost cut before..internal part was standard only upgrade 240cc+4g93t fuel pump and a FPR..boost 1 bar at this time..
now i'm using an oversize piston+safc..before using safc fuel press is around 3 bar and the car feel smooth at all range of rpm..nowadays i have to set around 70 psi(5 bar) just to get afr around 12.22 and boost around 1.3 bar..if i disconnect the one way valve can the fuel press set a bit lower?can i still boosting more than 1 bar after removing this one way valve?i'm planning to change the tebo and up boost to around 1.5-1.7 bar..can this be achieve just by changing to a much bigger injector and fuel pump?also planning to use a gsr injector(390cc) for this target..
the main question is can i remove the one way valve and still hitting more than 1 bar just by using a safc and bigger injector?
thanks bro..too late now cos i just bought the 390cc injectors a few days ago..still not put the injectors due to incoming upgrading..for time being i just will be using the old 240cc injector..now after removing the one way valve i'm facing problem to start my car..yesterday i have to crank about 5-10 min jun to get the engine running..this morning i have to push the car just to make it running..are they any means this prob could be related to the removal of the one way valve?strange enough after the engine run it will have no prob to start again if i shut down the engine..only if i let it park for more than 5-6 hours this prob will appear..removing one way valve on your map sensor will not effect your afr by much. changing to bigger injector will have a better result. 390cc with safc can boost more than 2 bar if you get the tuning correct. would recommend you to use 310cc injector.
